COOKING AND WASHING APPARATUS.

Too/ll whom it may concern.-

Be it known that 1, JOHN B. OONGER, a

citizen of the United States, residing at New is to be treated under pressure in a tightly-- closed vessel, like that employed in my invention. A serious objection to apparatus of this character'as enerally-constructed isthat the cooking is o lon duration throu h the fact that the steam ails to thorough y penetrate the mass which is to be cooked. A further objection to old forms of apparatus is that after the cooking operation has been completed it is necessary to remove the cooked mass to a separate apparatus for the purpose of thoroughly washing the disintegrating liquors from the same. A third objection to old forms of apparatus is that great difiiculty is experienced in removing or discharging the cooked mass from the cooking apparatus.

The first object of the present invention is to cause the" steam or other fluid which is rial to penetrate the entire mass, whereby the duration of the cooking operation is greatly decreased and the mass is cooked in a much more thorough and uniform manner than was formerly possible.

The second object of the present invention is to wash the cooked mass thoroughly and uniformly without the necessity of removing the same from the cooking ap aratus, so that any further processes to whic it may be necessary to subject the material can be completed in the same apparatus, whereby time which would be consumed in removing the mass to a separate apparatus is saved.

.The third object of the invention is to improve the construction of the cooking-receptacle in such manner as greatly to facilitate the removal of the cooked material therefrom.

. A further object of the invention is to support the cooking-receptacle in such manner that its size and capacity may be greatly increased without causing undue strain upon the supports thereof.

A further object of the invention is to avoid the use of interior mechanism in the cooling-receptacle which would retard. the proper agitation and uniform cooking of the material under treatment.

In the present construction the receptacle is charged intermittently through an opening in the side and is emptied intermittently by removing its lower end, the cylinder being inclined to facilitate the withdrawal of the contents from such end, and the receptacle is made air-tight to admit the use of steam under pressure, so as to operate most eifectively upon the contents, and the construction and o eration of the receptacle are both of them t erefore different from that of any openended cylinder employed for a continuous reception and discharge of the material in a continuous process.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the novel combination and arrangement of parts and in the details of construction hereinafter described and claimed.

In the accompanying drawing, forming part of this specrlication, Figure 1 is a side elevation of a cooking and washing apparatus constructed in accordance with the in vention. Fig. 2 is a vertical longitudinal section through the improved apparatus. Fig. 3 is, an. end elevation,partly-in section. Fig. 4 is 'a similar elevation showing the opposite end of the apparatus. Fig.5 is a detail section of one of the valves.

ceptacle 7 is mounted on an incline, as shown,

the material under treatment is easily and having an quickly discharged, this operation, if necessary, being facilitated by the rotation of the receptacle 7.

It will be understood that when the material under treatment has been thoroughly cooked by the use of steam or other suitable fluid and after the same has been washed said material can be readily subjected in the manner described to any other processes, chemicals, or the like which may be necessary or desirable in order to improve its condition. By using the improved apparatus of this invention, therefore, the material under treatment can be subjected in the receptacle 7 to a number of processes 7, which have heretofore necessitated the removal of the mate rial from one apparatus to another and sometimes through three or four sets of apparatus.

While the improved apparatus of this invention has been described as particularly intended for use in the production of paperpulp, it will be understood that said apparatus may be readily put to other purposes if desired.

By mounting the receptacle upon an incline and providing the same with a removable lower end the material can be discharged much more quickly and efiectively than is possible in apparatus where it is necessary to discharge the material through the same door by which it is introduced, as is common in air-tight rotary cookers.

By employing a plurality of injectors projecting into the receptacle the necessity of employing mechanism arranged interiorly of the receptacle for supplying steam is efl'ectually avoided, and consequently any undesirable interference with the proper agitation and uniform cooking of the material is prevented.

The improved apparatus of this invention is strong, simple, durable, and inexpensive in construction, as well as thoroughly efficient in operation.

Changes in the precise embodiment of invention illustrated and described may be made within the scope of the following claims without departing from the spirit of the invention. j
